Abstract
The Bureau of Mines estimated the cost for a uranium ion-exchange recovery system using five grades of u3o8 leach solution producing 815,570 pounds of u3o8 per year from an ammonium bicarbonate in situ leach solution. The system flowsheet consisted of four unit operations: (1) multiple-compartment ion-exchange (MCIX) absorption; (2) MCIX elution; (3) precipitation of the uranium as yellow cake, filtering, calcining, and packaging; and (4) waste disposal. The total fixed capital cost of a system treating 2,000 gallons per minute of 0.1-gram-per-liter-u3o8 leach solution was estimated as $6,888,000. For a basic case of an MCIX system depreciating in 9 years, unit production cost of u3o8 was $3.51 Per pound. A decrease in feed solution grade from 0.4 to 0.03 Gram per liter increased the production cost exponentially. Shorter depreciating periods significantly increased the production cost particularly for the lower grade feed solutions.
